基于混沌-分形理论的往复式活塞隔膜泵磨损故障分析（Wearing Fault Diagnosis of Reciprocating Membrane Pump Based on Chaos and Fractal Theory）
往复式活塞隔膜泵 磨损 故障诊断 分形 混沌
2010/5/5
针对往复式活塞隔膜泵磨损故障，采用混沌理论和分形技术，对隔膜泵不同连接处磨损时的系统非线性表现形式加以研究。通过对不同故障类型振动信号的分析，绘制了相应的庞加莱截面图，并计算了各种磨损故障的最大李雅普诺夫指数和关联维数。研究表明当没有磨损故障时，系统为准周期态；而隔膜泵的各种磨损故障信号呈现混沌性态，且不同故障状态的最大李雅普诺夫指数和关联维数有着较大的差别，可以用作其状态监测和故障诊断的特征参数...
